The “Who Will Save Your Soul” singer, 40, and professional rodeo rider, 44, married in 2008, after dating for a decade beforehand. They have a son, 2-year-old Kase, together.

“We both value growth,” she wrote. “And growth became tragically and undeniably stifled as a couple, and we believe we can find it again in setting each other free. We truly believe we can find greater happiness apart than together, and this is why we are taking the enormous and heartbreaking step of divorce.”

While their relationship may be coming to an end, Jewel and Murray are determined to focus on their son and hope to rebuild their friendship in the process.

“Our dedication to our son is unwavering and we are both committed to being the best partners in raising our son,” the couple said in a joint statement, also featured in Jewel’s blog post. “Due to the spirit in which we have gone about this separation, we trust we can remain dear friends who hold each other in high esteem, which is so important to us as parents—as we wish only what is best for our son.”
